There’s a tropical disturbance being referred to as Invest 93B…which is located approximately 63 NM south-southwest of Yangon, Myanmar

According to the JTWC…satellite imagery shows a consolidating broad mid level circulation with an associated low level circulation covered by deep convection on the western and southern sectors.

Despite the land interaction on the lower levels, environmental analysis indicates the invest is in a generally favorable area of development defined by low (5-10 knot) vertical wind shear, warm sea surface temperatures, and fair equatorward outflow.

Global deterministic models are in agreement that invest 93B will continue drifting eastward into the Gulf of Martaban over the next 48-72 hours, where it will gradually intensify before making landfall in Myanmar.

Maximum sustained surface winds are estimated at 23 to 28 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.
